Hello. Friend of mine kept bugging me to look at his problem. He has Gateway NV78 and tried to install ubuntu 12.10. Encountered backlight problem (he thought all was dead). Tried a few suggestions to no avail. The 'setpci' worked, but did not help after screen-saver/hibernate/etc. I have not had any real time to spend of this, nor look at source so... here is a pathetic work-a-round that got him working and not complaining: file: /etc/rc.local (add): if [ -x /lib/init/backlight_workaround ] then /lib/init/backlight_workaround fi create file '/lib/init/backlight_workaround' and chmod +x /lib/init/backlight_workaround put in file: /lib/init/backlight_workaround #!/bin/sh ( while sleep 1; do /usr/bin/setpci -s '00:02.0' 'F4.B=00'; done & ) & hope this helps someone else too.

[Bug 765438] Re: On startup, the backlight is off on laptop
Hello! Got semi-erratic troubles with the backlight too: Laptop Asus N76VZ Ubuntu 12.10 Starts with a medium- low luminosity so i made shortcut to (french language system): "parametres systeme , then : lumisosité et verrouillage" witch could be translated as something like "system configuration , light and locking". then suddently light changes to maximum, without any action on cursor. The standard control doesnt work well as when it goes to screen saving, it comes out with a very low light, thats why i look for work around. Been trying to restore keyboard keys for setting the backlight by installing xbacklight: sudo apt-get install xbacklight Did also at startup xbacklight =75 And then affected the lumisosity keys to, respectivly, xbacklight +5 xbacklight -5 This thing as been working , but is erratic , sometimes woks fine , sometimes my keys acting as a bistable switch , variing light with only two values. I'd like to use my keys shortcuts to adress this in a more direct way, like sending the right parameters to the standard program and uninstalling xbacklight. There is a problem somewhere. I fell like it could be related to broken communication between some programs , the variable related to light.

News: my guess is that it is still the randomness of the bug working around, or there has been a substantial improvements in recent kernels/Xorg drivers, but the bug is still present however in the past month EVERY time it occurred I could log in, suspend the computer (not hibernate), wake it up, and after usually one or two trials it went up again (in November/December it was not working even after 10 or 15 rounds). So now, as far as my Dell E4310 laptop is concerned, it is less critical.

[Bug 765438] Re: On startup, the backlight is off on laptop
Hi everybody - Dell Latitude E4310 / core i5 with intel graphics chip - LTS 12.04 This bug is VERY SEVERE on my laptop (actually, it is almost broken now and I will soon need a new one). reason: - when it happens there is no backlight and nothing to do, or almost - it is quite random. I tried almost all of the above tricks (stepci, boot options --- but not yet i915 invert brighness nor the change in rc.local, this is for next time it happens) and it does not work, or sometimes it does but it is never very clear what works, since the bug always reappears later - I tried (using an external display) : to echo 1 in intel_backlight/brightness, to manually (after login) increase the brightness, etc, etc. No effect. - I tried also Kamal's kernels (it was almost worst: sometimes instead of going blank in power save mode it was turning white) - Sometimes (not always) suspending / resuming works - sometimes rebooting works. last time I rebooted using a different kernel and it worked, I will check whether this is reproducible (next time I get the bug... but I'd rather never have it again) - sometimes unplugging the battery and waiting for some time works (not anymore, though, it seems) - sometimes nothing works and my laptop is unusable for some time - when the backlight is broken, it stays broken even when I boot Windows - Dell came and changed my display 1 month ago. Now Windows is broken (thanks a lot Dell, I was not using it very often but now I have no choice :-), but the bug happened again after a few weeks (bizarre, uh?) I'm afraid I will have to forget about using Linux if all recent kernels of all major distributions can break your computer. (But what? get a mac?? --- in fact I'll certainly get a different graphics system next time...) sorry for being so pessimistic, this is the first time I encounter such a severe problem under linux...

[Bug 765438] Re: On startup, the backlight is off on laptop
Notebook Acer TravelMate 5735Z-452G32MNSS 1) Ubuntu 12.10 (Quantal Queezal): The parameter i915.invert_brightness=1 fixes the bug! :-) Step-by-step - beginning from installation: - Boot with the Ubuntu Live-CD or Live-USB-Stick. - When the display becomes purple press CursorLeft or CursorRight. You see the menu. - Choose your language and press F6, then press Esc. - Put the cursor to the end of the line (after --) and enter: i915.invert_brightness=1 - Start the installation. At the end of the installation restart. - When the Notebook starts to boot again press Shift and hold the key unless the menu of GRUB appears. - Press the key e (e for edit). - Put the cursor after 'quiet splash', and enter after a blank: i915.invert_brightness=1 (Note: looks like: quiet splash i915.invert_brightness=1). Note: On my Laptop at this time the keyboard has the US-layout, not my common layout! - Press F10 to boot. - Open a terminal and enter: gksu gedit /etc/default/grub - Replace the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash“ by this line: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux acpi_backlight=vendor i915.invert_brightness=1" - Save the file. - In the terminal enter: sudo update-grub - After restarting my Acer TravelMate 5735Z works perfekt. It boots into a bright display. Also after waking up from hibernate and standby the display is bright. :-)) 2) Ubuntu 12.04 LTS (Precise Pangolin): The parameter i915.invert_brightness=1 doesn't work. But a workaround exists, that has the same result! :-) Step-by-step - beginning from installation: - Boot with the Ubuntu Live-CD or Live-USB-Stick. - When the display becomes purple press CursorLeft or CursorRight. You see the menu. - Choose your language and press F6, then press Esc. - Put the cursor to the end of the line (after --) and enter: acpi_osi=Linux acpi_backlight=vendor (Note: this is necessary to turn on brightness after booting by using the keys FN+CursorRight or Fn+CursorLeft). - Start booting (Option 'Testing Ubuntu without installation'). You will boot into a black screen. Press FN+CursorRight or Fn+CursorLeft to turn on brightness. Start the installation of Ubuntu using the icon on the desktop. At the end of the installation restart. - When the Notebook starts to boot again press Shift and hold the key unless the menu of GRUB appears. - Press the key e (e for edit). - Put the cursor after 'quiet splash', and enter after a blank: acpi_osi=Linux acpi_backlight=vendor (Note: looks like: quiet splash acpi_osi=Linux acpi_backlight=vendor). Note: On my Laptop at this time the keyboard has the US-layout, not my common layout! - Press F10 to boot. - Open a terminal and enter: gksu gedit /etc/default/grub - Replace the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash“ by this line: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux acpi_backlight=vendor" - Save the file. - In the terminal enter: sudo update-grub - In the terminal enter: gksu gedit /etc/rc.local - Above the line exit 0 enter: echo "1" > /sys/class/backlight/intel_backlight/brightness - Save the file. - After restarting my Acer TravelMate 5735Z works perfekt. It boots into a bright display. Also after waking up from hibernate and standby the display is bright. :-)) - Only one minor problem exits: In the case I use FN+CursorRight or Fn+CursorLeft to adjust the brightness, after waking up from hibernate or standby the notebook shows a black screen. So I have to press FN+CursorRight or Fn+CursorLeft once again to turn on brightness. After restart, everything works fine again.

The issue exists for me in Fedora 17, Ubuntu 12.04, Ubuntu 12.10, OpenSUSE 12.2, Debian 7, Linux Mint, LMDE, you get it. It's not a distrobution specific problem. I've tried many different APCI parameters in the grub menu and none of them have worked.

[Bug 765438] Re: On startup, the backlight is off on laptop
For me the issue is still present in Ubuntu 12.10. I'm on emachines e725, shortly after the Quantal Quetzel was out, I tried to boot from the original 12.10 32bit iso (tried out both creating a live usb and burning cd), was able to get just the black screen. After modifying the relevant files to set additional boot parameters "acpi_backlight=vendor i915.invert_brightness=1", got normally working startup disk. After installing Quantal I had to modify boot parameters also for the newly installed system's kernel. With these parameters set, the system functions normally, except for one case, when I recently closed the laptop's lid while an external monitor was connected. After raising the lid, laptop's backlight again was completely off; I was able to get it working by entering the command "setpci -s 00:02.0 F4.B=0" in terminal (thanks to the other monitor). I couldn't reproduce the problem since then, though. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/765438 Title: On startup, the backlight is off on laptop To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/765438/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 765438] Re: On startup, the backlight is off on laptop
I have only booted off the 12.10 32bit iso so far and have not installed, but the black display problem with the emachines e527 with the 12.04.1 iso does appear to be resolved "out of the box" with the 12.10 iso, using no additional kernel parameters or other modifications. However, while pressing the FN+arrow left/right keys displays the brightness slider on the screen and the slider responds to key presses, no corresponding change in actual screen brightness occurs. Adding (as I'm doing in 10.04) acpi_osi=Linux to the kernel command line when booting Linux makes the brightness adjustable, but disables the gui brightness slider display entirely. On 10.04, with that kernel option my arrow keys are properly assigned for adjusting the brightness, while on 12.10 they're backward. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/765438 Title: On startup, the backlight is off on laptop To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/765438/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I originally posted a duplicate bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/826386 regarding this issue. I recently downloaded Ubuntu 12.10 Quantal Quetzel. I made a startup disk using a USB flash drive to perform a fresh install and brightness was working "out of the box" no extra parameters were needed, no extra steps were taken. Brightness worked immediately, as well as the brightness controls. I have been running this installation for a week, updating software on a bi-daily basis and have had zero problems. I think this may be fixed.

Upstream is asking this: "Please try i915.invert_brightness=1 module parameter with kernel version v3.5 or later, see if that fixes the brightness issue, and report 'lspci -vmmnn' if it does."

[Bug 765438] Re: On startup, the backlight is off on laptop
I was having the problem on my eMachines E525, but the solution by cgonzalez solved this. To quickly recap what I did: I added "acpi_backlight=vendor" and "i915.invert_brightness=1" boot parameters. You add them by changing GRUB_CMDLINE_LINUX_DEFAULT value from "quiet splash" to "quiet splash acpi_backlight=vendor i915.invert_brightness=1" inside /etc/default/grub file. You then simply need to run `update-grub2` to update the GRUB bootloader, so that your new configuration is used next time you boot. Hope this helps. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/765438 Title: On startup, the backlight is off on laptop To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/765438/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 765438] Re: On startup, the backlight is off on laptop
This is a bug report, not a support forum. Please direct any support questions and solutions for installation and similar activities elsewhere. There are a lot of people subscribed to this bug and unnecessary bug mail does nothing but clutter the place up. To the more hostile: I advise you hop on the ubuntu bugs IRC channel the next time that you want a bug this important to you looked at for triaging - Someone will gladly take a look for you and triage it. I could have sworn that there was an earlier report that I had worked on - one that would make this one a duplicate. It contained very detailed info and links to upstream reports. I cannot for the life of me find it so I'm going to link it up on this one. Regardless, my bad; it slipped past my hundreds of bug reports. If the newer kernel does indeed fix the issue but only with a certain kernel parameter, please open a new bug report, link it here, and have everyone who is affect by that hop over there so that it's more organized. Again, please, this is a bug report and not a support forum. Comments should only be made if they are relevant to fixing the issue. Thank you. ** Bug watch added: Linux Kernel Bug Tracker #31522 http://bugzilla.kernel.org/show_bug.cgi?id=31522 ** Changed in: linux Importance: Undecided => Unknown ** Changed in: linux Status: New => Unknown ** Changed in: linux Remote watch: None => Linux Kernel Bug Tracker #31522 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/765438 Title: On startup, the backlight is off on laptop To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/765438/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Afternoon, I have been following this issue because I have not been able to use my laptop since April when 10.10 expired. If I try to install 11.10 on my e-machine now, will I have a backlight?

[Bug 765438] Re: On startup, the backlight is off on laptop
I have actually tried that patch (actually the slightly newer version of it found here: http://lkml.indiana.edu/hypermail/linux/kernel/1203.1/04190.html), without success. (Although possibly I did something wrong.) I followed the instructions located here: https://wiki.ubuntu.com/KernelCustomBuild (specifically the instructions starting at "MartinPitt: the easiest and best recipe that I found is to treat them as external modules, even when they are in-tree.") I had to apply the patch manually due to it being for a different kernel version, however I was able to get the module to compile successfully, installed in "extra", and after a "depmod -a" was able to successfully execute an "update-initramfs -u", but after rebooting with the "i915.invert_brightness" parameter passed to the kernel, behavior remained unchanged. Possibly my kernel was still loading the stock i915 driver though, I'll need to dig in to the init ramdisk image to confirm that it's actually using the patched drier as it's supposed to be. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/765438 Title: On startup, the backlight is off on laptop To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/765438/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 765438] Re: On startup, the backlight is off on laptop
Hi Kamal, I know you said "no change" reports aren't needed, and indeed I see no change in behavior over the stock 12.04 kernel with the above PPA. However, I had been using your previous PPA for 11.04 for quite some time successfully, and I definitely DID see a change in behavior from the stock 11.04 kernel with the kernels from that PPA, so I thought this an interesting enough regression to be worth mentioning. The symptoms that I have experienced with stock kernels (under both 11.04 and 12.04) is: - With no kernel parameters, system boots with backlight off, and brightness keys don't work. - With "acpi_backlight=vendor", symptoms are the same. - With "acpi_osi=Linux", system boots with backlight off, but the brightness keys work, so the backlight can easily be turned on and controlled, however the controls are inverted (I suspect this is why the system boots with the backlight off, since the kernel is trying to initialize it at full brightness.) I have been using this as a workaround. With your 11.04 series of kernels: - With no kernel parameters, system boots normally with backlight on, however brightness controls are inverted. With your 12.04 series of kernels: - Behavior is identical to stock kernel. The effected system is an eMachines E725 notebook, lspci output relevant to the video card follows.
